The drink offering was used in all of the offerings of the feasts as well as daily, weekly, and monthly offerings. It was also used with individual offerings since it always accompanied the grain offering. (See Numbers 15:1-12)
The amount of wine offered varied, not according to the offering but by the kind of animal used. The amount for each lamb or kid was 1/4 hin, for each ram 1/3 hin, and for each bull 1/2 hin.
(See Chart of Weights and Measures)
It seems that the drink offering was poured out at the brazen alter when the grain offering was offered.
The Drink Offering represented the blood of Yeshua, which was poured out for our sin atonement.
